SKElN NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 780,080, dated January17, 1905.

Application filed July 24, 1903. Renewed June 17, 1904:. Serial No.212,951-

J.o (l/ZZ/ whom, it Tit/t1 coll/corn,

Be it known that 1, WILLIAM; H. VVnBnu, a citizen of the United States,residing at Chicago, in the county of Cook, in the State of Illinois,have invented certain new and, useful lmprovements in Skein Nut-Locks,of which the following is a specification.

This invention relates more particularly to means whereby a nut for awagon-axle or similar purpose is prevented from being jarred or loosenedfrom its position on the threads. While it is particularly adapted forskeinnuts, I do not wish to limit it to this use, as it is evident itmay be adapted for other purposes. Its objects are to provide aconvenient means for the purpose indicated, which may be readilyattached to an ordinary nut and which may be adjusted to allow the nutto be unscrewed or screwed into place when desired.

it consists in the various novel features and details of construction,which will be set forth and claimed hereinafter.

In the accompanying drawings, illustrating this invention, Figure 1 is aside view showing a portion of the skein provided with a nut having mypreferred form of lock. Fig. 2 is an end view of the same. Fig. 3 is aside view showing a modified form of construction. Fig. 4 is an end viewof the device shown in Fig. 3.

A wagon-skein A is provided with the usual threaded portion a, which isengaged by the nut B. The skein is provided with a sheinbolt C,centrally located in the outer end thereof. At one side of the nut B isa lug D, to which is pivoted the nut-lock E. This lock is preferablyformed of a flat piece of suitable material, from which the ears 0 arebent down to engage the pivot-pin F, which passes through the lug D. Thelock E is su'liiciently long to take over the head of the sltein-bolt Cand for this purpose is cut away, as shown in Fig. 2 at e. The arms 6 ofthe fork thus formed by the cut-away portion are preferably turned outslightly at the ends in order to be easily engaged by the lingers forswinging the lock on its pivot. A spring down for forming the pivot.

G is secured to the pivot-pin and extends out to engage with a notch atb in the nut B and is then bent back to form a curved end portion .17,which engages with the upper end of the lock F, is adapted to hold thelock in normal position for engaging the head (J, and also for holdingthe lock in adjusted position, as shown in dotted lines in Fig. 1, whenit is free from the head.

, In the modification shown in Figs. 3 and L the nut B is provided witha lug D, to which is pivoted the lock E. This lock is also formed of asingle piece of metal and has lugs turned The portion of the lock whichis adapted to engage the skeinbolt head, or, as shown in Fig. 3, a lug Hon the end of the slzein, is flanged to form a cap or cover for saidbolt head or lug. The upper central portion of the lock is turned in, asshown at Ur, to form a spring -tongue which engages with the outer faceof the lug l) to hold the lock in normal engagement with the lug H andalso engages the upper part of the lug D to hold the lock in adjustedposition.

The operation is readily seen from the above description and thedrawings. hen the nut is to be turned on, the lock is swung out intoadjusted position in order to clear the bolt head or lug and is held inthis position by the spring. When the nut is screwed in place, the lockis pressed down to engage with the bolt head or lug and is held in thisposition by the spring.

Having thus described my invention, which I do not wish to limit to theexact details of construction herein shown, what I claim, and desire tosecure by Letters Patent, is

1. In a nut-lock, the combination of a nut, a lug on said nut, a forkedplate pivoted to said lug, a projection on the threaded portion withwhich said forked plate engages, a spring secured to the pivot-pin andsaid nut, having a free end adapted to engage with the heel of saidplate, to hold said plate in normal or adjusted position, substantiallyas described.

2. In a nut-lock, the combination of a nut, a

plate pivoted to said nut and provided With an plate in normal lookingor adjusted open poolpeninsg 1for enlgaglelriient Withtthe le-ad of1 asition, substantially as described. s ein- 0 t or tie i e, projec ingroni tie 1 threaded portion or skein, with which said WVILLIAM WEBER 5nut is adapted to engage, and a spring secured Vitnesses:
